You need to set up a network that needs to span multibple buildings. for this reason, you want to use the cabling that supports the longest maximum cable length. which network topology provides this?

Extended star topology

Explanation:

The Extended star topology also known as the tree topology comprises of characteristics of the linear bus topology and star topology.

It consist of multiple star connected topologies connected to a linear backbone bus topology. It has a wider communication area than the star topology and uses more cabling length. All the star networks are connected to a central connection which allows to have a full functioning network when others fails.
